Am I losing feelings for my boyfriend *Please read, I really need help*?

[The secrets that I keep]

I will try and make this as short as possible, it may be hard though
He's 17, I'm 16. We're both of legal age in the United Kingdom for sex.
I first met him through my best male friend, when we first met he was shy so we didn't talk. This was when I was 15 and he was 16.
He spoke to me continuously online, he seemed to like me and I adored speaking to him online.
We stopped speaking for a few months as alot of crap went down but in August of this year we began chatting online again.
I agreed to meet him at the end of August.
When we met up I was shocked, he looked so different (In a bad way) I didn't mind as I put this down to him being stressed over the past year.
He was nothing special at all, I couldn't believe that I'd lusted over him for a full year, I'd even become depressed on several occasions due to him..
He asked to meet me and on the second time we met he kissed me. He'd never kissed a girl before so it was very brave of him.
He asked me to be his girlfriend and I said yes.
A few weeks later we both had sex with each other, it was both our first times.
Now I sleep over at his house once a week and I've just noticed that I don't feel anything spectacular when I'm with him, I'm never incredibly happy to be with him; sometimes I just wish I was at home in my own bed.
The thing is; I hate the thought of us breaking up, the thought makes me really upset.
I still get incredibly excited when I see that he had inboxed me on facebook or sent me a text message and I don't know why, I'm never excited when speaking to him in person.
Is there something wrong with me? I'm never nervous when I'm with him, I just sometimes wish I could be some place else.
Thanks for any answers in advance

Same Thing Happend To Me it's Hard. But I Sort Out Feelings With My Boyfriend. & Maybe Your Just Still Not Comftrable Around Him Yet ? Or If I Were u Take Some Time Apart From Him Don't Break Up Just Go a Few Days Without Seeing or Talking To Him. If u Miss Him Then ur Just Going Through Emotions, if u Feel Better Then ur Probably Over him But Don't stay Because He Was ur first or Cause later You'll End up miserable. Sometimes Feelings Fade. . .

I think you just like the 'idea' of him...when you are texting and emailing him, you dont picture the guy that is really on the other side of the texts and emails...you have your own idea.
i was dating this guy for 11 months, and i never met him...it was strictly an online thing, we talked on the phone, he had a great voice, and we texted each other constantly and emailed all the time. we played random 2 player games together via online, he lived in minisota and i live in massachusetts; so the distnace was long...and neither of us had the money for a trip to visit one another.
i was in love with him...or i thought i was...whenever we video chatted, and when he sent me pictures, i had to pretend to like them, because i didnt find him attractive and there was never a spark when i saw him.
i soon realized i first fell in love with him because of his words...he was nice to me, and he cared about me...and he had so many plans and future ideas...and the thought of being alone really made me upset and uneasy (probably why the thought of dumping him makes you upset...)
anyways...if you arent sure about things...you should probably just take a break from the relationship for awhile; you dont want to date someone with no spark and no attraction for...if you wait to long, you could end up like i did.
the guy dumped me...i think he met someone else...but i wasnt prepared and i didnt know i would end up alone like this...and it ended up breaking my heart because now the perfect 'idea' of the guy i fell in love with....just feels like a complete lie...
dont let yourself get heartbroken...just talk to him about it...
